What if the air conditioner leaks?

When automobile air conditioner leaks, it should be considered from three aspects: air conditioning pipeline, compressor and expansion valve. Now, analyze the three causes of air leakage in air conditioning and the countermeasures to be taken. Solution: First, when there is a problem with the pipeline, consider removing and replacing these hoses. First, if the tightness of the compressor seal at the end of the stroke is insufficient due to the compressor problem, and the refrigerant at the end of the stroke is highly compressed, ultra-high pressure may occur. At this time, the sealing at the end of the steel drum is not strict, or trachoma will make the refrigerant leak. This problem is troublesome, and the compressor or parts need to be replaced. Secondly, if there is a problem with the expansion valve or a problem with a component with similar functions due to a problem with the expansion valve, the state of the refrigerant changes here, which is prone to problems. This is unlikely to happen. If it happens, change it. It shouldn't be too much trouble. However, it may be in the surface cooler, or there may be trachoma and cracks. In addition to the above methods, we should also deal with the air leakage problem of air conditioners at ordinary times and strengthen the maintenance of automobile air conditioners, so as to greatly reduce the air leakage of air conditioners. Maintenance method: 1. Be careful when modifying air conditioners: It is not recommended to modify automobile air conditioners, because the original air conditioners are matched with automobile engines. If you modify it at will, it will affect the performance of the car. Second, the air conditioning temperature should not be too low: choosing the appropriate air conditioning temperature is the first step of air conditioning maintenance. Third, control the direction of the air outlet: the principle of the air outlet of the automobile air conditioner: when the air conditioner is turned on, the air outlet will go up, and when the heating is turned on, the air outlet will go down. Fourth, don't turn on the air conditioner for too long: using the air conditioner for a long time will make the condenser pressure too high and cause losses to the refrigeration system. 5. Turn on the large air volume appropriately: air conditioners will inhale a lot of dust when in use, and regular strong winds can blow out the floating dust on the inner surface of the air duct. The simplest method is the most effective. 6. Turn off the air conditioner when driving at a low speed: Turn off the air conditioner as much as possible when driving at a low speed, and don't let the engine run at a high speed to improve the efficiency of the air conditioner in traffic jams, which will shorten the service life of the engine and the air conditioner compressor. 7. The switching procedure should be kept in mind: after each shutdown, turn off the air conditioner first and then turn it off. It is best to start the vehicle for two or three minutes, and then turn on the air conditioner after the engine is lubricated. Eight, slow down the long-term use of air conditioning in the hot sun: vehicles parked in the hot sun for a long time, the temperature in the compartment is higher. In this case, do not use the air conditioner immediately after the vehicle is started. First, open all the windows to ventilate and let out the hot air. After the temperature in the car drops, close the window and turn on the air conditioner. In addition, the air conditioner should not be turned on and off frequently to avoid damaging the air conditioning system. 9. Turn on the air conditioner in the car and try not to smoke: the car has stopped and the air-conditioned closed compartment is poorly ventilated. If you turn on the air conditioner to rest or sleep at this time, it is likely that the harmful gas emitted by the engine will leak into the car, causing poisoning and even life-threatening.
